Tömät

Tömít is a Hungarian verb meaning "to seal," "to stuff," or "to pack," commonly used in both everyday and technical contexts. As a technical concept, tömítés (the noun form) denotes a component or material used to prevent the passage of fluids, gases, dust, or other contaminants between mating surfaces.

In engineering and construction, tömítések include gaskets, O-rings, lip seals, mechanical seals and packing materials. These are made from a variety of substances—elastomers (rubber), PTFE, cork, metal, and composite materials—or supplied as liquid sealants such as silicone or polyurethane. Sealing methods rely on compression, adhesion, welding, or form-in-place materials to create a leak-tight interface.

Applications span plumbing, automotive engines, hydraulic systems, pipelines, valves, windows, and electronic enclosures. Key performance considerations are temperature range, chemical compatibility, pressure, wear resistance and ease of installation or replacement. Failures can result from material degradation, improper selection or installation, and mechanical deformation, and are commonly addressed through maintenance, monitoring and design changes.

In Hungarian usage tömít also carries non-technical meanings related to stuffing or packing (for example, filling food). Related terms include tömítés (seal/gasket) and tömítőanyag (sealant). The concept is comparable to the English terms "seal," "gasket" and "packing."
